Description
Technical field
This utility model relates to the design of frame for movement, relates in particular to a kind of for the ectoskeletal realization back of the body of assistance type frame and the stable two-stage hookup that is connected and can reliably carries of hip.
Background technology
Oscillation phenomenon is the natural phenomena of every engineering goods, fractures because of tremor as wing, and steel construction caves in etc. because of resonance, and this calls unfavorable factor; And for example jigging conveyer, vibrator etc. are favorable factor.Become the occasion of mechanical unfavorable factor in vibration, vibration damping and vibration isolation have more and more higher requirement, so the design of elastic damping system is the steps necessary of Machine Design equally.
For the ectoskeleton structure in the man-machine portable system, its major function is replacing human body to bear vertical load, so must tightly link together by connecting device between ectoskeleton and the human body.During man-machine portable, heavy burden can cause vibration and impact phenomenon with speed and the acceleration of human motion like this.When man-machine portable is walked, in the periodic movement that supports mutually and swing mutually, man-machine barycenter has the motion feature of a dipping and heaving, is rising or the heavy stage, and bearing a heavy burden all can cause dynamic loading by acceleration, and act on ectoskeleton repeatedly with man-machine barycenter curve, along with the increase of the speed of travel, the quickening of step frequency and the increase of stride, the frequency in this dynamic load effect cycle also can increase, amplitude can become greatly, causes ectoskeletal vibratory impulse.
Simultaneously during man-machine walking movement, swing provides side the hip phenomenon can occur hanging with respect to support-side, be that single foot is when supporting, heavy burden is supported by this side, the motion of opposite side then can not be restricted, otherwise can influence the harmony between the man-machine motion, this connecting device that just requires to carry on the back between frame and the hip should vertical support force, and the freedom of motion between the both sides again can not mutual restriction.
By the vibration that may be subjected to ectoskeleton and the analysis of percussion, and to the influence of between humans and machines harmony, require the design between ectoskeletal back of the body frame and the hip structure should satisfy load bearing requirements, can realize the decoupling zero of left and right sides hip again, satisfy the requirement of man-machine sports coordination.
In the research of present ectoskeleton frame for movement, emphasis concentrates on the design of lower limb load carrier and intensity, stiffness analysis, and often ignored problem between back of the body frame and the hip, and from the achievement in research of announcing, usually will carry on the back frame, left and right sides hip connects as a whole, can realize that human body is upright, the carrying under the static conditions, but then do not solve for the carrying such as the walking athletic posture of etc.ing, and the coordination exercise between man-machine does not have realization.
The utility model proposes a kind of new ectoskeletal realization of assistance type that is used for and carry on the back frame and the stable two-stage hookup that is connected and can reliably carries of hip, between back of the body frame and hip, the waist backplate is set as middle connecting device, and share a jackshaft, simultaneously at back of the body frame and backplate, be symmetrical arranged antivibrator between backplate and the hip structure, respectively the three is reliably connected, and the stretching action by antivibrator, can strengthen the stability of heavy burden, effectively reduce the shock loading of bearing a heavy burden and between man-machine moving period, ectoskeleton being caused, can realize the decoupling zero of the ectoskeleton left and right sides, effectively improve the harmony of man-machine motion.
The utility model content
